The R8500 has two ways to feed it power. There is the 4 pin connector
and the coaxial connector. I'm assuming for bench use, you attach a
13.8V to the coaxial connector. For gel cell use, you use the 4 pin
connector. However, the OPC-023C power connector, designed for mobile
use, goes to the 4 pin connector. So is it OK to feed 13.8V to the 4
pin connector?

You can use either connector, though I'd call it DC plug/socket connector
and not coaxial connector
If you need the instructionmanual I've got it he

Actually, that is called a coaxial power connector. Not the best
description in my opinion, but I didn't get to vote on it.

I already downloaded the manual, but it wasn't clear which connector
to use. On the R7100, you don't get a choice, so I am accustomed to
that power connector.

The 4 pin connector is used if you have 12 (13.8) VDC. The coaxial
connector is used for the AD-55 (A or E) adaptor which provides 16 VDC.

If you want to use 12 VDC you must use the 4 pin connector.

Thanks. I bought mine used and never got the official power supply. I
have been using the 4 pin connector.
